This is part 4 of the DSL irda how-to. In order to proceed from here, you will need to have irda up and running on your DSL machine as described in part 1 - see post "How to start irda & check it works"
In order to connect to the modem in your mobile phone over an irda connection, you need to first make sure that the irda mode on the phone is set to "modem" and not "pc-connect" or similar. Apparently, although the irda link can be used for dial-up and file transfers, it needs to be told which to expect.
I have been unable to use microcom or wvdial to make a GPRS connection but managed to figure out how to do this using chatscripts.
First create and save the following two files:
# cat /opt/ppp/peers/gprs_irda
# This optionfile was generated by pppconfig 2.1.
#
# /opt/peers/gprs_irda
#
defaultroute
noauth
connect "/usr/sbin/chat -v -f /opt/ppp/chatscripts/gprs_irda_chat"
debug
/dev/ircomm0
115200
updetach
#ipcp-accept-local
#ipcp-accept-remote
usepeerdns
# EOF
# cat /opt/ppp/chatscripts/gprs_irda_chat
# This chatfile was generated by pppconfig 2.1.
# Please do not delete any of the comments. Pppconfig needs them.
#
# ispauth chat
# abortstring
ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED
# modeminit
'' ATZ
#We add gprs specific stuff.
OK 'AT+CGDCONT=1,"IP","mnet"' [edit to suit your provider]
# ispnumber
OK-AT-OK "ATD*99***1#"
# ispconnect
CONNECT ''
# prelogin
# ispname
# isppassword
# postlogin
# end of pppconfig stuff
The connection can then be initiated by calling the gprs_irda file and terminated by poff:
# pppd call gprs_irda
Serial connection established.
using channel 1
Using interface ppp0
Connect: ppp0 <--> /dev/ircomm0

It took about 4 minutes to perform an "apt-get update" to the latest oldstable archive which seems pretty good to me.
Please feel free to suggest improvements to the chat scripts.
